Green Tourmaline Properties:
It is a very powerful healing stone. It helps bring harmony to one's heart by bringing balance and stability to the heart's energy field. It also helps align the heart's electromagnetic field to that of the Earth, bringing strength to the heart and helping the flow of healing energy around the body.
Agate Healing Properties:
 
Agate properties connect with the energy of the Earth. They are thought to bring harmony to all aspects of the being, physical, spiritual and emotional. Using agate during times of unbalance, when it feels as if the yin and yang within you are operating out of proportion, can reintroduce an equilibrium to your tempered soul.
